"I love renewables but I’m also pro-arithmetic"

This TEDx talk from physicist David Mackay is also well worth a watch. How do we wean Britain off its (current) 90% dependency on fossil fuels if we are serious about the shift to a Net Zero future? Many of the options, as Mackay argues, come with a lot of baggage. The answer lies with addressing both supply- and demand-side issues – changing our consumption habits; being more thoughtful about our energy usage; and finding friendly states with whom we can collaborate.
